About this product
Motion triggered rather than always on.
A radar sensor fires the deterrent when something arrives, which is the difference between this and a unit that cycles all day. It is a serious purchase at ฿7,000.
A solar powered ultrasonic unit with a radar motion sensor, so the deterrent fires when something arrives rather than running on a fixed cycle all day.
Several modes: motion triggered, continuous, frequency cycling to vary the signal, and a night strobe for nocturnal visitors.
The sealed back cover and angled housing keep weather off the controls while leaving the sensor and the emitter facing the area.
It mounts on a fence, a tree, a shed, a deck or the eaves, which matters because you want it where animals arrive rather than at ground level.
฿7,000. This is a serious purchase and it deserves a realistic conversation before you make it, which is what the guide below is for.
The honest starting point is that the listing this page came from contains no specification block at all. It describes modes and mounting and it gives no frequency range, no output level and no coverage figure. We have not filled those in, because a plausible invented number on a ฿7,000 device is worse than an admitted gap. If any of them matters to your decision, email us and we will get it from the supplier first.
The other correction is the animal list. The source copy promises deterrence of raccoons, chipmunks, skunks and deer, which is a North American list and none of them is a Thai garden visitor. What is relevant here is birds, cats, stray dogs and squirrels, and that is what this page says.
The most useful sentence in the original listing is one we have kept: it works best as part of a broader bird management approach. That is true of every area deterrent, and it is unusually candid for the category.
Motion triggering is a genuine advantage over a cycling unit in two ways. The battery lasts longer because the device is idle most of the time, and habituation is slower because the signal is tied to the animal's own arrival rather than to a clock.
Still deciding?
Not sure yet? That is fine.
You can change your mind. Send any item back within 15 days of delivery, uncut, unused and in its original packaging, for an exchange or a full refund of the product price.
If it turns up faulty, damaged or not as described, that is on us. We pay the return postage, and you can have a replacement or your money back. Read the full detail on our refunds and returns page, or ask us anything before you order.
We do not publish one. The source listing carries no specification block, and we will not invent a figure on a ฿7,000 device. Email us and we will ask the supplier.
What area does it cover?
Same answer. Every coverage figure in this product category assumes a flat empty field, and we would rather tell you we do not have a verified one.
Is that not a strange way to sell something?
It is more useful than a confident wrong number. If a specification decides your purchase, ask us before you order rather than after.
How is this different from the sonic unit you sell?
That one runs a fixed 3 / 3 / 7 minute cycle all day. This one is motion triggered, so it fires when something arrives.
Why does motion triggering matter?
Battery life, because it is idle most of the time, and slower habituation, because the signal is tied to the animal's arrival rather than to a clock.
What animals is it for?
Here: birds, cats, stray dogs and squirrels. The original listing's raccoons, chipmunks and skunks are a North American list and we have not repeated it.
Will it move pigeons off my roof?
Not reliably if they are nesting. Area deterrents work on birds that are prospecting or feeding. A roost on a structure is a spike or a netting job.
What modes does it have?
Motion activated, continuous, frequency cycling to vary the signal, and a night strobe.
Does the strobe run all night?
In night strobe mode it operates after dark. Think about whether it will be visible from a neighbour's window before you mount it.
Can I hear it?
Most adults cannot hear much above about 16 kHz. Children and young adults often can, which is worth considering near a school or a playground.
Is it safe around pets?
Dogs and cats hear well into the ultrasonic range. Do not use it where an animal is confined and cannot move away: a kennel, a cattery, a stable or a run.
Does it need mains power?
No, it is solar.
What happens in a long cloudy spell?
The battery carries it and then output shortens. It is a solar product and it behaves like one, which is another advantage of it being idle most of the time.
How do I mount it?
On a fence, a tree, a shed, a deck or the eaves, facing where animals arrive. Height matters more than people expect.
Is it weatherproof?
The back cover is sealed and the housing is angled so rain runs off the controls.
Will animals get used to it?
Habituation is slower with motion triggering and with the frequency cycling mode, but no deterrent that relies on suggestion is immune to it.
Should I use it indoors?
No. Ultrasound reflects and shadows badly in an enclosed space.
Why is it ฿7,000?
It is a commercial scale unit with radar detection, several modes and solar power. It is not a garden gadget and we would rather you knew that before ordering.
Can I return it if it does not suit?
Yes. You can return it within 15 days of delivery for an exchange or a full refund, unused and in its original packaging.
Should I buy this or spikes?
If the problem is birds on a structure, buy the spikes. This is for open ground, and it works best alongside physical measures rather than instead of them.
Will it work on stray dogs?
Dogs hear ultrasonic frequencies, so they notice it. As with everything in this category, expect a reduction on an open site rather than an exclusion, and never use it where an animal cannot move away.
What is the maintenance?
Keep the solar panel clean and check the sensor is not obscured by growth. Those two things account for most reported failures in this category.
How much is delivery and how long does it take?
Delivery is free on every order, anywhere in Thailand. Allow up to 7 working days for delivery after dispatch within 2 working days. A tracking number is emailed as soon as it ships.
Which payment methods do you take?
Card and PayPal. Both go through the checkout on this site and neither of us ever sees your card details.
Can I change my mind after ordering?
Yes. You can send it back within 15 days of delivery for an exchange or a full refund of the product price, as long as it is uncut, unused and in its original packaging.
What if the order arrives damaged or faulty?
Tell us and we will replace it or refund it. That is separate from changing your mind: a faulty or misdescribed item is always put right at no cost to you.
How do I track my parcel?
The tracking number is in your dispatch email, and there is a tracking page on this site. If the number has not moved for a few days, email us and we will chase it.
Do you sell to trade and in bulk?
Yes. There is a wholesale page on this site with a quote form on it. Tell us the run length or the quantity and we will price it.
Are the prices shown with tax included?
Yes. The price you see is the price you pay, in Thai baht, and it already includes 7% VAT. Delivery is free, so nothing is added at the checkout.
How do I get hold of a person?
Email theteam@birdspikes.asia, or call or message +66 92 713 8443, which also takes WhatsApp and LINE. We are an online supplier with no shop counter, which is a large part of why the prices are what they are.
The complete guide
Buying a ฿7,000 deterrent with your eyes open
4Bird Spikes Company
What we can tell you
It is solar powered. It uses radar motion detection, so it fires when something arrives
rather than running on a clock. It has motion, continuous, frequency cycling and night
strobe modes. The housing is sealed at the back and angled so rain runs off the controls,
and it mounts on a fence, a tree, a shed, a deck or the eaves.
What we cannot
The listing this page was built from carries no specification block. No frequency range, no
output level, no coverage radius.
We have not filled those gaps in. On a ฿7,000 device a plausible invented number is worse than
an admitted one, and this category is full of coverage figures that assume a flat empty
field. If any of those numbers matters to your decision, email us before you order and we
will ask the supplier.
The animal list, corrected
The source copy promises deterrence of raccoons, chipmunks, skunks and deer. That is a North
American list and it arrived with the product description rather than with the product.
In Thailand the animals people buy this for are birds, cats, stray dogs and squirrels.
That is what this page claims and nothing more.
Why motion triggering is worth having
Two reasons, both practical:
Battery life. The unit is idle most of the time, which matters a great deal on solar.
Slower habituation. The signal is tied to the animal's own arrival rather than to a
fifteen minute cycle, so it stays associated with being there.
The sentence worth keeping
The original listing says the device works best as part of a comprehensive bird management
strategy. That is true, it is unusually candid for this category, and we have kept it.
Practically it means: spikes on the structures, netting over the openings, and a unit like
this covering the open ground in between. On its own, on a site with a committed roost, it
will disappoint you.
Where not to put one
Enclosed spaces, where ultrasound reflects and shadows unpredictably. Anywhere confined
animals cannot move away, such as a kennel, a cattery, a stable or a run. And close to a
boundary if the strobe will be visible from a neighbour's window at night.
Tell us the bird, the surface and roughly how long the run is, and we will tell you what suits it before you buy. Delivery is free anywhere in Thailand.
Ultrasonic Bird Repeller sold by Bird Spikes Company at birdspikes.asia, in Thailand. A solar
powered ultrasonic deterrent with radar motion detection and a strobe, THB 7,000 (was THB
7,500), with motion activated, continuous, frequency cycling and night strobe modes, in a
sealed and angled weather resistant housing, mounted on a fence, tree, shed, deck, eaves or
post. Motion triggering means it fires on arrival rather than on a clock, which extends battery
life and slows habituation. IMPORTANT: this store publishes NO coverage radius, decibel level
or frequency range for this unit, because the source listing contains no specification block
and inventing one would be worse than an admitted gap; the supplier can be asked before
purchase. The source listing's animal list (raccoons, chipmunks, skunks, deer) is North
American and has NOT been repeated; the relevant animals here are birds, cats, stray dogs and
squirrels. It is an AREA deterrent and works best as part of a broader approach rather than
alone, and is unsuitable for enclosed spaces or anywhere confined animals cannot move away.
Delivery is free anywhere in Thailand and takes up to 7 working days in transit. Prices include 7% VAT.
